WINDSCREEN FOR MOTOR VEHICLES AND THE LIKE Filed Nov. 28. 1928 W m @ff bwmwwiuw Patented Sept. 9, 1930 PATENT OFFlQE HERBERT AUSTIN, BROMSGROVE, ENGLAND I WIND SCREEN FOR MOTOR VEHICLES AND THE LIKE Application filed November 28, 1928, Serial No. 322,549, and in Great Britain December 10, 1927.

This invention relates to wind screens of the type described in my former patent specification No. 1,618,746 that is to say in which there are two lights an edge of one of which a is arranged to be moved laterally in relation to an edge of the other a packing being provided attached to one of such edges; and the invention has for its object to provide an improved or modified construction of the means for effecting the packing.

In my former specification a length of resilient tube was laid within a concave edge (as seen in cross-section) of one of the lights of the screen, the said edge being preferably curved lengthwise in a slightly convex curve. The tube Was, according to one modification, described as retained in place by a wire in tension which passed endwise through the tube and was secured at its ends in relation to the light or the frame of the screen.

According to the present modification, the edge of the light against which the tube is secured, in lieu of being hollowed as seen in cross section, is left flat or is of convex curved form and the wire is replaced by a strip of a channel-like section preferably rounded, the hollow being towards the said edge of the light. The strip is laid within the tube in such a manner that it holds it on to the rounded edge thereof. The tube is preferably of a diameter somewhat greater than the thickness of the light, so that the strip can press the tube over the edges. In this case the width of the strip should be somewhat greater than the thickness of the light to secure the best results. The corresponding or contacting edge of the other light bears against the tube in the manner clescribed in my former specification, its edge being preferably rounded so as to indent the tube somewhat.

In order that the invention may be clearly understood, a convenient application thereof is described with reference to the drawings herewith, of which Figurel is a fragmentary View in elevation, but partly in section, to illustrate a portion of a wind screen arranged according to this invention; and,

Figure 2 is a sectional view to an enlarged scale, the section being taken on the line 2, 2, of Figure 1.

In these drawings, A is the lower and B the upper light each formed as a sheet of glass. C is a rubber tube placed between the edges of the two sheets, and held down against the upper curved surface a of the sheet A. by means of a metal strip D which is of an inverted and rounded channel form as seen in section. The strip D is laid along the inside of the tube C and is tensioned at one or each end by a nut E which screws upon a reduced end F of the strip D at the said end. The sheet B is rounded at its lower edge, and, when swung into the same plane as the glass A, bulges the tube in somewhat as seen at G, and secures a weather-tight joint.

Owing to the shape, in cross-section, of the strip D being concave at its under surface, it keeps the tube G in contact with the sheet A without the necessity for making the upper edge of the sheet convex as seen in front elevation. This permits of the sheet B being swung about a centre which is near to its lower edge if desired, without breaking the joint with the tube.

It will be seen by reference to Figure 1 that the strip D is somewhat wider than the thickness of the sheet A, whereby the tube C is caused to overlap the sides of the sheet A to some extent.

Having fully described my invention, what I claim and desire to secure by Letters Pat ent, is

1. A window or windscreen comprising two lights of transparent material, two adj cent edges of which are adapted to be brought together or moved laterally apart when desired, a resilient tube, a metal strip passing through the tube, a hollow in the side of the strip which is towards the edge of one of the said lights, said strip being wider than the thickness of said light at the edge thereof, means for keeping the strip taut within the tube, means for attaching the strip at its ends in relationship to the said light and said edge being rounded as seen in cross-section whereby said Wide strip will cause the wall of said tube to overlap the front and back faces of said light somewhat.

2. A window or wind screen comprising two hghts of transparent materlal, two ad acent edges of which are adapted to be brought together or moved laterally apart when desired, a resilient tube a metal strip passing through the tube, a hollow in the side of the strip which is towards the edge of one of the said lights, means for keeping the strip taut within the tube, means for attaching the strip at its ends in relationship to the said light said edge being rounded as seen in cross-section and said hollow'being of such width as will cause the wall of said tube to overlap the front and back faces of said light to some extent. I

In witness whereof I have hereunto signed my name this twelfth day of November, 1928.
